I'm looking to upgrade my family car and boat and was wondering if a new 2009 Toyota Sequoia can tow this boat....thanks. If not what vehicle could?

The Sequoia will NOT be able to tow it.
Currently, there is no SUV able to tow this boat.
The Cadillac Escalade has the highest rated towing capacity of any SUV at 7,300 LBS. The boat weighs 9,000 LBS according to their website.
You are going to have to get a diesel truck such as a Silverado 2500, or F350.
